Write the following quadratic function in standard form and then sketch its graph. Clearly mark on the graph the vertex and all intercepts.

f(x)=-2x^2+6x+15

Note: if you could include step by step explanations so I’ll be able to understand the process and learn this concept that would be great!!

Given quadratic equation is:

We can write it as:

So given equation is:

On comparing with :

Where (h,k) is vertex of given equation.

SO in given equation vertex of given equation is:

For x intercepts we can equate given equation to zero.

So we will get

So or

So x intercepts are or .

For y intercept we can write x = 0 in given equation

So y intercept is 15.
